To ail whom, it may concern.-

Be it known that 1, WILLIAM ENGLAND, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Sea-Cocks; and I do hereby declare that the following is afull, clear, and exact clescription of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon. which form part of this specification.

My invention has reference toa sea cock or valve for vessels; and it has for its object certain improvements in the arrangement and construction of such devices whereby the same are incapable of freezing when the vessel is laid up for the winter.

A further object consists in so arranging the working parts of the device that they may be readily detached for the purpose of repairs or inspection without the inconvenience and expense of docking the vessel.

A further object consists in providing an extended inlet into the device for the entrance of water, with positive means for effectively sealing said inlet.

With these and such other objects as will hereinafter appear my invention is constructed, and it comprises the novel combination and arrangement of the parts hereinafter shown, described, and claimed.

In the accompanying drawings, Figure 1 is a top plan view of a sea-cock constructed in accordance with my invention. Fig. 2 is a sectional view on line w m, Fig. 1. Fig. 3 is a view showing the cover of the main-valve casing removed, together with the main-valve stem and the valve-plate, the auxiliary valve being shown in closed position, the section through the casing of the auxiliary valve being indicated by the line y Fig. 1. Fig. 4 is a section through the main-valve casing on line 2, Fig. 1, the main-valve plate being shown in position within the casing. Fig. 5 is a view of the vessel plating orsheathing perforated to receive the sea-cock.

Referring to the details of construction, 1 indicates the main-valve casing, preferably of rectangular shape, having the base-flange 2, through which extend bolts 8 to secure the sea-cock to the vessel-sheathing 4, the latter being provided with a multiplicity of perforations 5, arranged close together in the form of rectangle corresponding to the shape of the interior of the casing 1.

6 is a flanged connection leading from one end of the main-valve casing and adapted to connect with the main service-pipe of the vessel.

The outer margin of the casing 1 is flanged at 7, and 8 is a removable cover or closure for the casing, arched outwardly, as shown, and having a marginal flange 9, adapted to connect with the flange 7 and be secured by means of bolts 10. Arranged to extend trans versely above the cover of the casingis a strong-back 11, comprising a bar 12, supported at its outer ends upon the main-valve casing by means of studs 13, suitably bolted thereto.

14 indicates a rectangular-shaped valveplate of the main valve provided with a facing 14, of rubber, rubber fabric, or other suitable compressible material, adapted to seat upon the perforated section of the vesselsheathing and close the perforations 5 therein. The valve-plate 14 is adapted to move through the casing 1 and take the position in dotted lines in the casing-cover, being actuated by means of the screw-threaded valvestem 15, working in a screw-threaded perforation in the strong-back and having a handwheel at its outer end, a stufling-box being provided in the casing-cover around the valvestem to prevent the leakage of water from the interior of the main-valve casing. The inner end of the valve-stem 15 is operatively connected with the valve-plate 14 by means of a swivel-joint 17. In constructing the valve-plate 14 I employ a plurality of flat metal bars 18, connected in parallel relation to form a rectangular-shaped structure by means of transverse bars 19, the center bar 19 carrying the socket 20 of the swivel-joint 17 the outer bars being provided centrally with eyes 21, adapted to connect with the forked ends of guide-rods 22, guided through stuflingboxes 23 in the casing-cover, the

strong-back 11 being also provided with alined perforations 24, through which the guiderods 22 extend, being free to move lengthwise therethrough. The perforations 24 are screwthreaded to receive set-screws 25, which when the main valve is closed are adapted to engage the end of the guide-rods 22, and consequently force the outer ends of the valve-plate into contact with the perforated sheathing of the vessel.

26 indicates the auxiliary-valve casing, extending laterally from the main-valve casing, being detachably secured thereto by means of bolts 27. Extending centrally through the outer end of the casing 26 is the auxiliaryvalve stem 28, surrounded by a stufiing-box,

and at its inner end the valve-stem 28 is swiveled to the auxiliary-valve plate 29, having a forming a seat for the auxiliary-valve plate when pressed against the same by the pressure of the water within the main-valve casing. This flange is formed entirely around the casing at its upper end adjacent to the casing-cover, the passage therethrough being rectangular in shape and of a size to permit the unobstructed movement of the main-valve plate.

The auxiliary-valve stem is rotated and the valve-plate connected therewith operated by means of a hand-wheel 32.

The operation of my improved sea-cock is as follows: While the vessel is in commission the auxiliary-valve plate will be withdrawn from the main-valve casing, taking a position within the casing provided therefor. The main-valve plate will also take a position within the cover of the main-valve casing, so that the water may pass through the perforated sheathing of the vessel and without obstruction into the main service-pipe connected with the casing 1. When the vessel is to be laid up for the winter, the main valve is closed by turning the hand-wheel upon the main-valve stem, causing the main-valve plate to be forcibly pressed against the perforated sheathing of the vessel, the compressible facing thereon being forced into the perforations 5. To insure the absolute sealing of all of the perforations, the outer extremities of the valve-plate remote from its connection with the valvestem are forced into contact with the perforated sheathing by the action of the set-screws 25 engaging the ends of the guide-rods 22, the set-screws being screwed into the perforations in the strong-back after the guide-rods have been drawn into the same. Since the main-valve plate is constructed of a plurality of metal bars having more or less resiliency, the same will the more readily adjust itself to any curvature in the vessel-sheathing, this curvature being considerable in some vessels. It is apparent that the pressure directed centrally of the main-valve plate by the valvestem would in very large valves be insufficient to effectively seat the valve-plate at its outer extremities. This is, however, effectively accomplished by connecting the guide-rods at the outer extremities of the valve-plate and forcing the same down by means of the setscrew 25 engaging the ends thereof. The guide-rods are also provided to guide the mainvalve plate in its movement through the easing 1 to insure the proper registry of the same with the rectangular group of perforations in the vessel-sheathing and also to guide the valve-plate in passing through the rectangular opening surrounded by the flange 31 on the interior of the casing 1. Since the main valve is now effectively closed to prevent the entry of water into the casing 1, the water remaining in the casing may be withdrawn by opening the waste-cock 33. The auxiliary-valve casing and the auxiliary-valve plate therein can now be removed for the purpose of inspection or repairs, and the same may be permanently detached from the main-valve casing throughout the entire period that the vessel is laid up. Should any injury occur to the compressible face upon the main-valve plate, so as to require repairing, the auxiliary valve is placed in position, when the main valve may be operated to cause the main-valve plate to take a position within the cover 8, the position which it then assumes being shown in Fig. 2. The parts are now relatively disposed to permit the auxiliary valve to be operated to close the passage from the main-valve easing into the cover 8. The cover 8, together with the main-valve stem and its valve-plate, as well as the strong-back, are now removed, the auxiliary-valve plate being in the position shown in Fig. 3, with its margins seated upon the flange 31.

It will be seen from the foregoing description that any of the working parts of my improved sea'cock may be readily detached for the purpose of inspection or repairs without the necessity of docking the vessel and that the valve when operated as herein directed will be free from the danger of freezing.

Although I have specifically illustrated a preferred embodiment of my invention, I do not intend thereby to limit the scope thereof, since it is apparent that changes and modifications in detail may be made therein without constituting a substantial departure.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

1. A sea-cock comprising a casing secured over a suitable opening in the sheathing of the vessel, a valve-plate within the casing adapted to fit over the opening in the sheathing, said valve-plate comprising a facing of compressible material and a backing of a plurality of bars held in parallel relation by a series of transverse bars, a socket disposed centrally of the valve-plate and eyes adjacent to the outer margin thereof, an operating-stem swiveled in the socket for reciprocating the valve-plate, and guides secured to the eyes.
